What 


SANIU UNI DIC Ee 
Is 


“Alundum” is the trade-mark name 
for an abrasive product used ex- 
tensively in the manufacture of 
grinding wheels for machining steel, 
steel alloys and other materials. As 
the cutting agent in grinding wheels 
and sharpening stones and as a 
medium for polishing metals this 
abrasive material has become a 
vital factor in the metal industries, 
where grinding in recent years has 
taken a prominent place among the 
metal machining operations. 


It is a product of the modern elec- 
tric furnace, made by fusing the 
mineral bauxite. In chemical terms 
it is oxide of aluminum, Al2O3 in 
crystalline formation. In chemical 
composition Alundum abrasive is 
the same as the ruby and sapphire. 


Its remarkable qualities for resist- 
ing wear are due to a peculiar 
combination of hardness and tough- 
ness which are valuable requisites 
in such products as the grinding 
wheel, which must stand up and 
resist wear under the severest kind 
of service. 


The same wear-resisting properties 
which have made Alundum abra- 
sive products so vital to the metal 
industries throughout the world 
make it a desirable material for use 
in a floor tile. It has greater wear- 
resisting qualities than any known 
material used in floorings.

HE accompanying color plates show only a few of the 

many possible color combinations obtainable in this 

tile. With the great variety of marble chips and the 
various colors of Alundum Safety Aggregates available, you can 
readily appreciate the color possibilities. 


The engraver and the printer have quite satisfactorily reproduced 
the samples submitted to them. If you were looking at one of 
the tile instead of the picture you would note that it has a slip- 
proof surface. Alundum Aggregates give it the slip-proof and 
non-wearing qualities. The aggregates are composed of Alun- 
dum abrasive grains bonded together with clay by the vitrifying 
process, crushed and screened to standard sizes. They are made 
in the following colors: brown, buff, gray, cream and dark green. 


Alundum Safety Aggregate Tile is made by modern machine 
methods in one of the largest abrasive manufacturing plants in 
the world. Marble chips and Alundum Aggregates are bonded 
together with cement and are ground to a true level surface. 
The facilities for meeting special requirements are practically 
unlimited. We have adopted the usual standard sizes, 8’, 9’’, 
LOS eandel 2. sequates..o: xo . 9 x 18” and 10 x 20’ oblongs. 
If desired, we can furnish risers, threshold and sanitary base 
tile to match, or of such color as will harmonize. 


The introduction of this safety tile for flooring has made it 
possible for the architect to choose the combination of colors 
desirable for any type of building, both interiors and outside 
entrances; plus the non-slip, wear-resisting surface and one that 
can be readily cleaned. 


The trade-mark under which it is sold has stood for high quality 
in abrasive products and refractories for many years and that 
trade-mark on a tile is in itself a guarantee of high quality. 
If you have in mind any particular job and will give us an idea 
what color you wish for the floor, we will select from our many 
samples a specimen that will be near your choice.
